실험 절차

To a solution of methanol (8.5 mmol) and triphenylphosphine (2.6 g, 8.5 mol) in dry THF is added a solution of ethyl 2-((N-(butyloxycarbonyl)sulfamoyl)amino)acetate from the previous step (2.4 g, 8.5 mol) and DIAD (2.0 g, 8.5 mmol) in dry THF dropwise at 0° C. under N2 atmosphere. The mixture is stirred at 0° C. for 2 h, warmed to RT and is stirred overnight. After the solvent is removed in vacuo, the residue is purified by column chromatography to afford ethyl 2-((N-(butyloxycarbonyl)-N-methylsulfamoyl)amino)acetate.
